Vol. VIII] VAN DUZEE—NEW SPECIES HEMIPTERA 281 



Color sanguineous, obscured on the vertex and pronotnm; clypeus, an- 

 tennae, legs, callosities, clavus, inner field of corium, membrane and genital 

 segments black; vertex, at least posteriorly, and disk of pronotum more or 

 less infuscated, the collum, sides and median line remaining paler. An- 

 tennae in the male testaceous with the first segment and narrow base of the 

 second black ; third and fourth in the female often paler. 



Described from one male and ten female examples taken 

 from the flowers of a bush sunflower growing along the road 

 at Soboba Springs, near San Jacinto, Calif., June 1, 1917. 

 Both this species and nigridavus vary considerably in the ex- 

 tent of their dark markings but the characters given seem suf- 

 ficient to separate them. 



Holotype (No. 395), male, allotype (No. 396), female, and 

 paratypes, in collection of the California Academy of Sciences. 



11. Neurocolpus simplex, new species 



Allied to mexicanus, proportionately shorter and broader 

 than nubihts with basal segment of antennae and hind femora 

 more thickened ; color yellowish, inclined to fulvous, the hairy 

 vestiture white. Length 6^2 to 7 mm. 



Head about as in nubilns, the tumid vertex scarcely projecting beyorid 

 the line of the clypeus. Basal segrnent of antennae clavate, shorter than in 

 nubihis and thicker at apex than in either of our other species, its hairy 

 vestiture silvery white, the hairs less flattened than in the allied forms; 

 second segment almost twice the length of first, shaped as in nubilus, less 

 clavate than in mexicanus; third and fourth together subequal to first, 

 slender. Pronotum as in nubilus, its length one half its basal width, clothed 

 with short matted scale-like hairs ; collum not so strongly distinguished as 

 in the allied species. Rostrum reaching to apex of the intermediate coxje. 

 Abdomen somewhat expanded, the connexivum surpassing the elytra in 

 some examples. 



Color obscure fulvous or honey-yellow, becoming clearer yellow on pos- 

 terior disk of pronotum, apical lobe of scutellum, and base of elytra ; the 

 whole surface clothed with a white vestiture of scale-like hairs which show 

 an inclination to form three lines on the vertex, to become somewhat 

 matted on the pronotum, and are larger and more conspicuous on the legs. 

 Membrane whitish hyaline with the nervures yellowish, becoming more or 

 less infuscated at base. Sometimes there is a faint fuscous cloud on outer 

 margin of membrane before its apex. One immature example has the apex 

 of the tibiae and of the embolium greenish. 



Described from four females taken on the palo-verde, Cer- 

 cidiiim torreyamim, among the foothills west of Coachella, 

 Calif., May 16, 1917. This species is very distinct in its pale 

 color, white vestiture and the form of the antennal segments. 



Holotype (No. 397), female, and paratypes in the collection 

 -of the California Academy of Sciences.
